No, it's 2wd! You need a 4X4 trans to bolt to a t-case. Somebody who knows what they are doing can convert a 2wd C6 to a 4X4 but it would probably cost more than a good used one.

460, 400 and 351M bolt pattern is the same.

Good luck.

does a t18 and c6 need different adapters to the 205? considering going to a manual. basically i have a stock 460 burned up c6 and a good 205 keep breaking stuff just put in a dana 60 with yukon inners and outers and a detroit with drive flanges but of course now i break driveshafts would like to go to a small block of some sort just trying to weigh all options kinda stuck with driver side drop transfer case after all the money that went into the dana 60

Rebuilding the c6 you have is probably your most economical choice, and there is no reason it can't be built to hold up behind a big block.

well i'm thinking get rid of big block and go small block tranny went out not because of horsepower it was under cooled just weighing options of motor tranny combo's

What year is your truck? EFI?

Tons of stuff needs to be changed to put a 302, 351W or 351C in there. If it's not EFI give up the small block idea and put in a 351M or a 400, they're practically a bolt in.

To change a 2wd C6 to 4wd you have to swap the rear output shaft and tailhousing for a transfercase adapter. There are two lengths, so rear output shaft must match the transfercase adapter.

That requires complete transmission un-assembly btw.
